AC Dripping Repair: A Complete Guide and How to Find a Professional Repair Company

Contents

When summer arrives, air conditioning becomes a lifesaver for many people, but dripping water from the AC often causes trouble and may even require professional AC repair services.

AC Dripping Repair | Causes of AC Dripping

AC dripping is usually caused by the following reasons:

Blocked drain pipe

Condensation produced during operation is usually discharged through the drain pipe, but when dirt, dust, or other foreign objects block the pipe, drainage cannot proceed smoothly and the air conditioner may drip water. Possible causes of a blocked drain pipe include:

Dust build-up due to long periods without cleaning;

The air filter has not been replaced regularly;

Damage inside the pipe allows foreign objects to enter the pipe.

Damaged drip tray

The drip tray is inside the air conditioner and mainly collects condensate. If the tray cracks or is damaged, the condensate cannot drain properly, causing the AC to drip. Possible causes of drip tray damage include:

Ageing or material deterioration;

Wear caused by improper installation;

Damage caused by physical impact.

Improper AC installation

The air conditioner must be kept level to ensure condensate flows smoothly into the drain pipe. If the installation is improper or the unit is uneven, water flow may be blocked, causing the air conditioner to drip. Possible reasons for improper installation include:

Installer error;

Loose bracket or screws affect AC balance;

Environmental factors, such as uneven walls or an unstable floor.

Poor heat dissipation

When an AC does not dissipate heat properly, it may produce excessive condensation. In such cases, even if the drain pan and drain pipe are normal, the unit may still leak water. The possible causes of poor heat dissipation include:

Clogged air filter;

Excessive dust on the fins;

Abnormal outdoor unit operation.

AC Dripping Repair | AC Dripping Repair Methods

Depending on the cause, the following methods can be used to repair AC water leakage:

Clean the drain pipe

Do not use a regular household vacuum cleaner to suck up water, or dismantle the internal pipes to try to clear a blockage. Residents may record dripping and any visible blockage from a safe position. How to clean the drain pipe, pump, and drip tray should be assessed by service staff; switching off the unit does not make every internal operation safe.

Make sure the power is switched off to avoid electric shock;

Use cleaning tools of the proper size to avoid damaging the drain pipe;

After cleaning, check whether the drain pipe is clear.

Replace the drain pan

If the drain pan is damaged, it needs to be replaced with a new one. When replacing it, please note the following:

Choose a drain pan suitable for the air conditioner model;

Replace according to the manual or the guidance of a professional;

After replacement, check that the drain tray is securely installed and that there is no water leakage.

Adjust the installation angle of the AC unit

If the air conditioner is installed improperly, the installation angle needs to be adjusted so that it remains level. Please note the following when adjusting:

Please have a professional make the adjustment to avoid damaging the unit;

After adjustment, make sure the bracket and screws are tight;

Check whether condensate can drain smoothly.

Improve heat dissipation

If heat dissipation is poor, you can take the following steps to improve it:

Regular cleaning of air filters;

Remove dust build-up on the heat sink;

Check the outdoor unit in operation, and if anything is abnormal, have it repaired by a professional.
